Patented Sept. 1, 1931 SUETEE STATES PATENT @FE'HQE JOHN D. PEDERSEN, OF. JACKSON, WYOMING Application filed August 13, 1929. Serial No. 385,608.

This invention relates to cartridge clips of the enbloc type adapted to hold a double row stack of cartridges arranged in staggered relation, and one of the objects of the invention is to provide a reversible clip of this character so that it may be charged with its stack of cartridges either end up into the magazine of the gun.

The clip may be made of any suitable material but is preferably formed of spring metal so as to provide spring pressed sides which will hold the stack of cartridges with a clamping pressure and, together with the cartridges, constitute a firm packet for being carried outside of the gun as well as for being charged into the magazine.

It will be understood that the present clip is adapted for use in a magazine type of gun having a suitable follower for feeding the cartridges upwardly through the clip into position for being loaded. Accordingly, the present clip is designed for the proper holding and guiding of the cartridges therein during the above feeding operation.

The clip is preferably provided with means adapted to coact with elements of the gun for holding the sides of the clip in spread relation during said feeding operation and to prevent the contraction of the clip sides upon a partially depleted stack after one or more of the cartridges have been loaded therefrom.

Further advantages and improvements in the invention will become apparent from the following detailed description taken in connection with the accompanying drawings which show the preferred embodiment of the present invention and in which:

Fig. 1 is a side elevation of the clip and stack of contained cartridges forming a packet;

Fig. 2 is a vertical section taken along line 2-2 of Fig. 1 to show more particularly the retaining portions and holding shoulders of the clip ings, the clip, preferably made of spring metal, comprises a back 1 with spring pressed sides 2 and 3 extending forwardly therefrom and providing a receptacle for a stack of cartridges which will be open at the top, front and bottom thereof. The back and sides of the clip are preferably of thin metal out out in places for lightness and suitably stiffened as required by upset stifiening ribs thereof.

In carrying out the purpose of the invention in making the clip reversible, I have preferably designed the functional elements of the clip so as to be symmetrical both as respects the opposite sides of the clip and as respects the top and bottom of the clip. The cartridges (C 0 C etc.) are held within the clip in staggered relation, as shown, to form a double row stack and the universal character of the clip is such that it will make no difi'erence in its function whether the two rows of cartridges are stacked right-handedly in the clip (as shown in Fig. 2) with the right row in higher position, or whether the clip is filled left-handedly with the left row in higher position.

The back of the clip at its top and bottom is cut out at 4, 5 (as shown) to provide passage for the loading element of the gun (viz.

he bolt) in picking off the top cartridge of the stack in the loading operation. The back of the clip may be provided at a central position thereof with a latching. shoulder 6 adapted for engagement with a suitable retaining latch of the gun (not shown) in holding the clip in the magazine.

Each of the sides 2 and 3 of the clip is exactly alike in shape and form. Referring to side 2, this has an integral inwardly eX- tending curved portion 7 at its upper end and a similar portion 8 at its lower end, which portions 7 and 8 serve as cartridge retaining portions. The side 3 has similar and oppositely facing cartridge retaining portions 9 and 10, respectively.

Spaced approximately by the radius of a cartridge from the upper end of the side 2 is a holding shoulder 11 for a cartridge formed by an outwardly upset recess portion 12 in said clip side. A similar shoulder 13 with recess 14- is provided adjacent the lower end 8 of said clip side 2, also similar shoulder 15, recess 16, shoulder 17 and recess 18 are formed on the clip side 3 adjacent the upper end 9 and lower end thereof, respectively.

Projecting from the forward edge of each clip side 2 and 3 and also preferably midway between top and bottom of said sides are narrow lips 19 and 20, each with an inwardly projecting bump 21 and 22 formed by upsetting said metal inwardly. The purpose of these projecting portions and bumps 19, 21. and 20, 22 is to provide means for preventing the contraction of the sides of the clip when one or more of the cartridges are removed therefrom in loading. It will be understood that these projecting bumps 21 and 22 will be engaged by elements of the gun (not shown) when the clip is inserted in the magazine thereof and will coact with said elements either to spread apart slightly the sides of the clip and relieve the tension thereof on the contained stack of cartridges or be merely held in position against contraction.

Each side of the clip 2 and 3 has formed thereon adjacent the back 1 a vertically extending and inwardly projecting rib 23, 21, which ribs are adapted to engage in the usual manner behind the extracting shoulders of the cartridge bases. In the example shown, the cartridges are provided with grooves at their bases adapted to be engaged by said ribs 23, 24 and thus assist in holding the cartridges firmly in the clip.

A full stack of cartridges held within the clip may be disposed therein as indicated in Fig. 2 and it will be observed that the top cartridge of the stack is engaged by the cartridge retaining portion 7 of one side 2 and the bottom cartridge of the stack by the cartridge retaining portion 10 of the opposite side 3,also that the next to the top cartridge will be engaged by the holding shoulder of the side 3 and the next to the bottom cartridge will be engaged by the holding shoulder 13 of the side 2. It will further be noted that the inward pressure of the portion 7 upon the top cartridge throws it slightly to the left from the line of its column and that the next to the top cartridge is likewise thrown slightly to the left of the line of its column, whereby said latter cartridge seats partially within the recess 16 and thus be comes more securely engaged by the holding shoulder 15. A similar. action occurs with the bottom cartridge and the next to the bottom cartridge in connection with the respective lower portions of said clip.

In the feeding of the cartridges upwardly through the clip for loading, a suitable follower of the gun (indicated in dotted lines at F, Fig. 5) will exert an upward pressure upon the stack and feed the same upwardly step by step as each'successive cartridge is picked off the top thereof. I have shown an ordinary type of stepped follower in connection with the disposition of the cartridges in Fig. 5; but it will be understood that for the complete utilization of the universal character of my clip wherein the cartridges may be stacked either with the left row higher or the right row higher, a special form of follower should be employed having a switchable upper step portion such as is shown and described in my copending application Serial No. 339,916, filed February 14, 1929.

Referring again to Fig. 2, after the top cartridge C for the stack has been picked off in loading, the stack will be moved upwardly by the follower and the cartridge G will easily pass its shoulder 15 and engage with the cartridge retaining portion 9 and will move slightly to the right in so doing. Cartridge C in its upward movement, will also be thrown slightly to the right for lirm engagement with the shoulder 11. This action is repeated throughout the feeding of the stack and it will be clear that the provision of the cartridge retaining portions and shoulders as shown will serve to hold and guide the top cartridges of the stack into their proper position for loading.

It is obvious that various modifications and changes may be made in the structure shown without departing from the spirit and scope of the invention as hereinafter claimed.
